Description of the programme

These interlaboratory comparisons (AGLAE's programme ‘1A’) in public drinking water, surface waters or bottled waters are provided in the frame of:
  • accreditation scopes related to physico-chemical analyses in drinking waters (check AGLAE's accreditation - Cofrac No. 1-1664)
  • approvals issued by Departments of environment or Ministries of Health

An identical proficiency testing is also conducted at lower concentration levels to meet specific requirements.
